[+/-] : Flame Retardants

Flame Retardant are substances that can be chemically inserted into the polymer molecule or be physically blended in polymers after polymerization to suppress, reduce, delay or modify the propagation of a flame through a plastic materials. There are several classes of flame retardants; Halogenated Hydrocarbons (Chlorine and Bromine containing compounds and reactive flame retardants), Inorganic flame retardants ( Boron compounds, Antimony oxides, Aluminium Hydroxide, molybdenum compounds, zinc and magnesium oxides ), Phosphorous containing compounds (Organic phosphate esters, phosphates, halogenated phosphorus compounds and inorganic phosphorus containing salts).

[+/-] : ANTIMONY TRIOXIDE

Antimony trioxide is produced from stibnite ores (antimony trisulfide) or as a by-product of lead smelting and production. It is used mainly in fire-retardant formulations for plastics, rubbers, textiles, paper and paints.

It is also used as an additive in glass and ceramic products and as a catalyst in the chemical industry. Occupational exposure may occur during mining, processing and smelting of antimony ores, in glass and ceramics production, and during the manufacture and use of products containing antimony trioxide.

Whiteness	95% MIN

Features

• In flame retarding thermoplastics, the synergistic action between halogenated flame retardants and antimony trioxide is well known in the plastic industry.
• The Izod impact strength and translucency are two key properties that are diminished because of the particle size and pigmentation strength of antimony trioxide.
• The loss in translucency limits the range of available color choices because of the high loading required to offset the tinting effect of antimony trioxide.

[+/-] : Low-smoke Halogen-free Flame Retardant Master-batches

Low-smoke Halogen-free Flame Retardant Master-batches-FR-GML-1 Type, FR-GML-2 Type

Our company recently developed FR-GML Type of low-smoke halogen-free flame retardant mater-batches. It is a kind of master-batches flame retardant produced with Magnesium Hydroxide as main flame retardant compounded with high-effective flame retardant initiator and synergist. FR-GML flame retardant master-batches is quite different from the traditional one, developed on the base of environmental protection, low-smoke, innoxious magnesium hydroxide, this kind of flame retardant could fit breadth of processing temperature, which greatly strengthens its adoptability to polymer materials of high processing temperature. Meanwhile, it could strengthen the thermal stability of flame retardant polymer materials, decrease burning smoke generation and improve the performance of polymer materials like mechanical strength.

FR-GML-1 Type flame retardant master-batches is a common type and the oxygen index could reach 27%-33% with appropriate addition.

FR-GML-2 type flame retardant master-batches is a kind of high-effective flame retardant material. The oxygen index of the material could reach 35%-45% after addition of the master-batches. Customers could choose accordingly.

The flame retardant efficiency to polymer material of fill flame retardant represented by Magnesium Hydroxide and Alum Hydroxide is comparatively low, while FR-GML type flame retardant master-batches challenges the low flame retardant efficiency of the fill flame retardant and marched out an essential step to the fill flame retardant properties of low-filling and high flame retardant efficiency. FR-GML is trying to produce satisfying flame retardant effect required by polymer materials with possibly less filling quantity with polymer material performance degrades as less as possible. Meanwhile, the compatibility of FR-GML and polymer material is quite positive, which minimize the degrading of polymer material performance and therefore widen the use span of the FR-GML flame retardant master-batches.

FR-GML flame retardant master-batches has properties of wide application scope, strong adoptability and user-friendly. It owns quite good flame retardant efficiency and compatibility to PE, PP, PA and PC. Its use quantity varies from 20% to 70%. Users could choose appropriate quantity according to the polymer materials, which needs to be retarded, to reach different flame retardant level.
